Then the weak formulation of the control equations considering the contact constraint conditions has been developed. Combined the Lagrange multiplier and penalty function methods, the augmented Lagrangian method is used to treat the contact constraint and solved the non-linear and non-smooth problems of the mechanical response perfectly. A finite element model has been applied for the test project of the reinforced slope and to study the mechanism of the interaction of the soil and reinforced material.

本文在Lagrangian网格的控制方程中引入接触界面条件，并采用了经典的Coulomb摩擦模型作为界面切向面力的本构模型，继而发展了考虑接触约束条件的控制方程的弱形式；在求解方法上，综合了Lagrange乘子法与罚方法的优点，采用增广的Lagrangian方法处理接触界面约束，很好地解决了接触问题中的高度非线性和响应不平滑性。

Based on observation data, the development process of the breach of landslide dams due to over topping may divided into 3 modes: vertical erosion, breadthwise extension and regression erosion of dam slope. A mathematical model describing the gradual failure process of the landslide dams is established based on the formula expressing the high intensity erosion obtained from experimental data, which can integrate the 3 modes of breach development process together. The validity of the model is verified by observation data.
